Digital Temperature Sensor DS18B20 with wire 1m, watertight

This Digital Temperature Sensor with the Dallas (Maxim Integrated) 1-Wire Interface measures temperatures between -55 and +125 degrees Celsius. The highest precision of +/- 0.5 deg. can be found in the range of -10 to +85 degrees Celsius.

Libraries for this sensor type and different programming environments, for example for Arduino or Raspberry, are available and easy to find.

The sensor element is limited watertight, since the used shrinking tube does not have melting glue inside. The use of an additional piece of shrinking tube with glue would result in a definitely better watertightness.

The digital sensor element can be programmed for resolution of 9 to 12 bits (steps of 0.5 to 0.0625 degrees), a 12 bit conversion takes max. 0.75s.

A temperature alarm condition can be programmed right in the sensor (nonvolatile).

Every sensor element comes with a unique, digital serial number. Therfore, multiple sensors can be connected to the same 1-Wire interface.
